. Claims.

This invention relates to sliders for use in coupling and uncoupling the stringers or chains of separable fasteners. More particularly, the invention relates to what is termed lock sliders employing a spring wire lock element which also forms means for coupling a finger piece or pull with the slider, whereby in moving the slider in both directions on the stringer, the lock element will be moved by the finger piece or pull into inoperative position. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 is a plan view of a portion of two stringers showing one 'of my improved lock sliders thereon.

Fig. 2 is a perspective view tached; and,

Fig. 3 is a section on the line 3-3 of Fig. 2.

With lock sliders of the general type and kind under consideration, the construction of the slider as well as the lock element has been some-, what costly and has usually presented, on the wall of the slider, a protruding body which has been objectionable from the standpoint of increasing the over-all thickness of the slider and presented difliculties from the standpoint of laundering garments to which the fastener has been attached.

It is the purpose of my invention to provide not only an inexpensive lock slider construction, but also one which presents a reasonably flat upper surface which permits free passage of the slider through laundering apparatus, particularly ringers, ironers and the like.

In Fig. l of the drawing, I have shown for the of the slider depurpose of illustrating the general adaptation.

of the invention a small section of two stringers with one of my improved sliders arranged thereon. w represents the stringers or chains, to the beaded edge portion of which are attached the links or scoops II which are coupled and uncoupled by a slider l2 movable longitudinally of the stringers or chains.

The slider i2 comprises a channeled body formed by a, top wall l3 anda bottom wall 14' joined at the wide end of the slider by a connecting web or frog 15. The top and bottom walls have, at side edge portions thereof, inturned flanges it which engage the links or scoops H oi the stringers. 4

The outer surface of the top wall i3 is provided with a transverse groove or recess II, the walls of which curve upwardly and outwardly where they meet the fiat surfaces l8 and I! of the narrow and wide end portions of the slider. Two transversely spaced apertures 20 are formed in the wall l3 and these apertures open outwardly through the surface i8 and into the channel 2| of the slider.

Arranged upon the surface I!) is an outwardly projecting rivet pin portion 22, which is arranged within and spaced from a raised yoke-shaped wall or flange portion 23 having the more or less parallel ends 23a extending in the direction of the narrow end portion of the slider, as clearlyseen in Fig. 2 of the drawing.

In the construction shown, the slider isin the form of a die casting and, when so made, the pin 22 is an integral part of the casting andis cast unheaded and is afterwards headed over, as seen at 24, note Fig. 3, in securing the spring wire member 25 in position.

The member 25 form what may be termed a combined lock elementand pull mounting. In the construction shown, the member 25 is formed from a single strand of material, the central portion of which is shaped to form a ring 26 en circling the pin 22 .and fitting within the ring portion 21 of the wall or flange 23. Extending from the ring portion 25 are two rods 28 arranged in parallel relationship to each other and terminating at their ends in laterally directed extensions 29 having downwardly directed pin portions 30 at the ends thereof.

The :pin portions 30 form the lock elements of the slider which extend through thea apertures 20 into the channel 2| by the normal spring properties of the member 25. Rods 28 are held' in close proximity to each other between parallel. ends 22a of the walls or flanges 23. These rods form, in conjunction with the recess 11, the loop for receiving and coupling the finger piece or pull 3| with the slider. In the construction shown, it will be apparent that the pull 38 will lie-flatly along the slider within the limits of the member 25, as indicated in Fig. 3 of the drawing. Asa matter 01' fact, the entire structure of the slider produces a flat surface in alinement with outer surfaces of the member 25 and the'wall or flange portion 23 being modified only by the slightly protruding head 24 of the coupling pin 22; This fiat construction adapts the slider for use on appanel which may require laundering.

The rods 28 of the member may be unattached in certain uses. However, in other uses they may be secured together in any desired manner.

' It will be understood that, in operating the slider along the stringers, a pull on the flnger piece, 3i will operate upon the rods 28 to raise the lock elements or pins 30 out of the channel II of the slider, thus providing free movement of the slider on the stringers. In this flexure of the member 25, the rods 28 are free to pass vertically between the wall portions 230, the pull being assisted in this operation by the upwardly curved wall portions of the recess i'l. 5

It will be apparent that the transverse alinement of the portions 30 may be staggered with respect to each other to flt between links of opposed stringers. In this connection, it will also I be understood that when the spring arms or rods 28 are unattached, each element 30 will be capable of independent operation in assuming a locked engagement with the links of the strin ers. Asa matter offact, one element 30 is sumcient to produce the desired locking of the slider and from this standpoint only one element need, in fact, be employed.

In assemblage'of the member 25 with the slider, it will be understood that the looped end 28 is placed in the recess formed between the wall 23 and the unheaded rivet pin 22. When the member is in this position, with the rods 28 disposed between the extensions 23a and the pins 30 in the apertures 20, the rivet pin 22 is headed, as at 24, securely retaining the member 25 against displacement.
